World No. 8 Alex de Minaur is set to face the unseeded Leandro Riedi in an unexpected Round-4 battle at the 2025 US Open. The Australian has had a fairly straightforward journey in the competition so far. He won his first two matches in straight sets, and then won the third due to retirement. On the other hand, Leandro Riedi has been one of the most surprising breakout stars of this year’s US Open. Will his golden run of upsets continue? Let’s look into the details of this match-up, using the great odds provided by BetMGM.

Alex de Minaur vs Leandro Riedi Match Preview

Alex de Minaur has a 40/15 record in 2025, and won the title in Washington DC. One of the most noteworthy critiques of the 26-year-old, is how he needs to discover the level that can truly turn him elite. Yet, de Minaur is among the most consistent players on tour for an extended period of time now. The 8th seed has the pace and accuracy of groundstrokes to dismantle any opposition. In form and well rested at the moment, this is not good news for Riedi.

Speaking of Leandro Riedi, the 23-year-old is on an epic run at Flushing Meadows. Despite this being just the second major tournament for the World No. 435, the Swiss star has shown great persistence over the past week. Having failed to earn a tour-level win prior to the US Open, Reidi’s wins over Johns, Martinez, Cerundolo and Majchrzak have checked off a successful campaign. However, Riedi’s relative inexperience naturally makes him an underdog – not just against de Minaur but against most of the remaining contingent in New York.

Alex de Minaur vs Leandro Riedi US Open 2025 Prediction

Unless something miraculous occurs, Reidi’s dream run is likely to end on Monday. The Swiss sensation will struggle to find answers on the de Minaur serve, and the suffocating pace of the Aussie will draw unforced errors from the unseeded campaigner. His only saving grace could be a high percentage of first serves, which may help him take the game deep. However, a straight sets victory is inevitable in our eyes.

Prediction: Alex de Minaur in straight sets.
